摘要

PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that has excellent low-temperature fixability and charging characteristics.SOLUTION: A toner for electrostatic charge image development contains a binder resin, and the binder resin includes a block copolymer having a crystalline polyester block and an amorphous polyester block. When a melting point peak area based on the crystalline polyester block of the toner measured by a differential scanning calorimeter is Q1, and a melting point peak area based on the crystalline polyester block of the toner after one-week storage at 50°C measured by a differential scanning calorimeter is Q2, Q2/Q1 satisfies the following formula (1): 1.0≤Q2/Q1≤1.2.
